Afternoon Update: Steady rain becoming more light and showery the rest of Monday
Updated: 12:45 p.m. Feb. 27, 2023Rain is becoming more scattered up to about Milwaukee. That's a trend that will take over this afternoon. By the evening commute the rain is over. But it's already been a record setting day. Milwaukee now has 2.02" of rain today, smashing the old record of 1.17" set back in 1948. Even for the entire month of February we average 1.69" of precipitation. Pretty astounding when you look at it that way. Here's a handful of other reports, all over one and a third inch. While we dry out lingering flood issues will remain. The heavy snowpack from the last snow/sleet event is preventing some of the rain from soaking into the ground. At this time you can expect to encoutner lots of ponding on roads. Flood concerns also hover over poor drainage areas. Typical trouble spots like the Root River at Raymond and Oak Creek/South Milwaukee have flood warnings ongoing for another couple days in some cases. Just use common sense and turn around versus trying to navigate through flooded areas. Here's the latest on the alerts:

The heavy steady rain in communities south of I-94 is coming to an end but still some light steady rain for a few more hours. Some heavy rain still remains in northern Fond du Lac and Sheboygan Counties and other northern counties still have a little freezing rain or wintry mix. Any ponding and flooding on area roadways should subside over the next few hours.
Rain totals so far Monday morning have surpassed an inch in southern areas and half inch in northern counties. Rain totals in some communities could touch 2" by the time the rain is done. Expect another 0.10-0.50" of rain the rest of the day.

Steady rain has rolled into southeast Wisconsin since 3 AM early Monday morning. This rain continues to roll north and has now reached our far northern counties. Most of the rain is steady and heavy. Most of Walworth County and the surrounding area is waking up to some good thunderstorms as well.
So far, temperatures have remained above the freezing mark of 32* reducing any threat for freezing rain or wintry mix but radar is showing some pockets of light ice in parts of Washington and Fond du Lac Counties. A Winter Weather Advisory remains in effect until noon for the potential for light ice Monday morning.
The rest of the forecast shown below including rain totals remains on track.

After a beautiful weekend, heavy rain will move in to start the work week. Widespread steady rain will move into southeast Wisconsin between 5-7am and continues steadily through the noon hour.
While this will be plain old rain for most of the area, temperatures in Fond du Lac and Sheboygan counties will be below freezing, so a couple hours of freezing rain or sleet is possible through the morning commute. With some icing possible, a Winter Weather Advisory has been issued for those counties from 4am to noon Monday.
Steady rain will taper to isolated rain showers in the afternoon as the center of the low pressure system tracks across SE WI. A few wrap around snow showers are possible NW of Milwaukee in the evening before precipitation ends.
A solid .75"-1.25" of rain is expected across southeast Wisconsin with a majority of that rain falling between 6am-12pm.
With a frozen ground and 1-2" of liquid currently in the snow that is on the ground, we could be dealing with some ponding or flooding on Monday. MMSD has also issued a Water Drop Alert for Monday, meaning reduce the amount of water you use to help prevent basement backups or sewage overflows. So yes, you can put of doing laundry and the dishes for another day.
On top of the rain, we'll also be dealing with 30-40 mph wind gusts in the morning and again in the evening.
